Arrays and Cooperative Transceivers for Wireless Localization and Communications

The increased demand for high data-rate and mobile wireless services, and the desire for more reliable coverage and connectivity dictate better understanding and modeling of the propagation channels, and the exploitation of various possible mechanisms for bandwidth-efficient signal separation and/or diversity through the design of multi-element antennas (arrays) at the receiver and/or transmitter. Arrays also provide the opportunity to localize mobiles for emergency or location-based services and/or for monitoring. Following general introductions to this topic, examples of statistical and ray-based channel models that are useful for wireless communications and wireless localization in urban settings are presented. This is followed by an overview of distributed multiple-antenna systems that are variously known as collaborative, cooperative or mesh systems, which use fixed or mobile relays for providing enhanced connectivity and transmission diversity.
